Abstract
The two dish induction installation of CD of the present utility model, comprise support, transport tape, induction mechanism, it is characterized in that: its induction mechanism is fixed on support by hinge contact epimere, gap between hinge contact hypomere base and transport tape is in 0.2-1.1mm scope, hinge contact hypomere and contacts mates, form the mechanism that clutch produces signal; Have that structure is simple and direct, cost is low, high reliability, effectively can identify two dish, and can not judge by accident because of impurity, guarantee normal production.
Description
Technical field
The utility model relates to the two dish induction installations of a kind of CD and two dish inducing method, especially can distinguish two dish and impurity by failure-free, guarantee that CD printing does not affect production by erroneous judgement.
Background technology
In current CD printing, two dish induction great majority adopt the induction of correlation optical fiber.Consult Fig. 4, the two dish induction installation of a kind of CD generally includes support 1, fix screw 2, structure of fiber_optic 3, laser transimitter 4 and laser pickoff 5, CD transport tape 6 is positioned at structure of fiber_optic 3 middle, the normal CD 7 of normal transport is positioned at the groove of CD transport tape 6, the upper surface of normal CD 7 is parallel with the surface of transport tape 6, the center of laser transimitter 4 is higher than the surface of transport tape 6, and distance is not more than 1.2mm.
Consult Fig. 5, in the two dish induction installation of the CD shown in Fig. 4, improper CD 8 is stacked on normal CD 7 and causes two dish, the thickness of improper CD 8 is 1.2mm, be greater than the distance between the center of laser transimitter 4 and the surface of transport tape 6, two dish is when structure of fiber_optic 3, and the laser that laser transimitter 4 sends can be stopped by improper CD 8, laser pickoff 5 cannot receive laser, trigger alarm device.
Consult Fig. 6, in the two dish induction installation of the CD shown in Fig. 4, due in presswork process, ink 9 is often had to drop on transport tape 6 and normal CD 7, at this moment when ink 9 is by structure of fiber_optic 3, also laser pickoff 5 can be made to receive laser, cause inductor to judge by accident, thus the normal production of impact.
Retrieve through Chinese publication, do not find the scheme identical with present patent application.
Summary of the invention
The technical matters solved: in order to the two dish induction technologies overcoming prior art well can not distinguish the deficiency of two dish and impurity, the invention provides a kind of induction two dish induction installation and a kind of two dish inducing methods using this device more accurately.
The two dish induction installation of CD of the present utility model, comprise support, transport tape, induction mechanism, it is characterized in that: its induction mechanism is fixed on support by hinge contact epimere, gap between hinge contact hypomere base and transport tape is in 0.2-1.1mm scope, hinge contact hypomere and contacts mates, form the mechanism that clutch produces signal.Gap between described hinge contact hypomere base and transport tape, preferably in 0.5-0.6.mm scope.
The utility model solves the technical scheme that its technical matters adopts: a kind of two dish induction installation, comprises support, fix screw, hinge contact epimere, hinge contact hypomere and contact.Support is positioned at directly over transport tape, and hinge contact upper semisection is fixed on structure of fiber_optic, and hinge contact lower semisection contacts with contact, and the bottom of hinge contact is parallel to transport tape surface, and keeps certain interval, and gap is less than video disc thickness.Fix screw and contact are connected the both positive and negative polarity of sensor circuit respectively.When equipment normal operation, hinge contact lower end contacts with contact all the time, though have the impurity such as ink drop on above also cannot push contact open.When there is two video disc, because second piece of video disc thickness is greater than the gap between contact and rotating disk, at this moment contact can be pushed open by second piece of video disc, hinge contact lower end is up tilted, depart from contact, cause sensor circuit open circuit, make equipment alarm, feed back to the running of PLC arrestment, reach the object of the two video disc of induction.
The present invention compared with prior art its beneficial effect is: have that structure is simple and direct, cost is low, high reliability, effectively can identify two dish, and can not judge by accident because of impurity, guarantee normal production.

In figure: support (1), fix screw (2), structure of fiber_optic (3), laser transimitter (4), laser pickoff (5), transport tape (6), normal video disc (7), improper video disc (8), ink (9), hinge contact epimere (10), hinge contact hypomere (11), contact (12).
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail, but embodiments of the present invention are not limited thereto.
The two dish induction installation of CD of the present utility model, as Figure 1-3: support (1), fix screw (2), structure of fiber_optic (3), laser transimitter (4), laser pickoff (5), transport tape (6), normal video disc (7), improper video disc (8), ink (9), hinge contact epimere (10), hinge contact hypomere (11), contact (12).Its all parts all can buy or adopt prior art manufacture to obtain; Complete machine can adopt prior art to assemble.The two dish induction installation of CD of the present invention, comprise support, transport tape, induction mechanism, it is characterized in that: its induction mechanism is fixed on support by hinge contact epimere, gap between hinge contact hypomere base and transport tape is in 0.2-1.1mm scope, hinge contact hypomere and contacts mates, form the mechanism that clutch produces signal.Gap between described hinge contact hypomere base and transport tape, preferably in 0.5-0.6.mm scope.
Refer to the two dish induction installation preferred embodiment of the utility model shown in Fig. 1 and Fig. 2, this induction installation comprises support (1), fix screw (2), hinge contact epimere (10), hinge contact hypomere (11) and contact (12).
In the present embodiment, support (1) is positioned at directly over transport tape (6), hinge contact epimere (10) fix screw (2) is fixed on the middle of support (1), the bottom of hinge contact hypomere (11) is parallel to transport tape (6), and keep certain gap, contact with contact (12).Hinge contact epimere (10) is connected sensor circuit both positive and negative polarity respectively with contact (12).Normal video disc (7) surface overlaps with transport tape (6) surface, can not touch two dish induction installation.
Refer to Fig. 3, when two video disc is through out-of-date, improper video disc (8) thickness 1.2mm is greater than the gap between hinge contact hypomere (11) and transport tape (6), improper video disc (8) pushes hinge contact hypomere (11) open along with the motion of transport tape (6), hinge contact hypomere (11) is up tilted, hinge contact hypomere (11) is separated with contact (12), sensor circuit open circuit, start two dish abnormality alarm, feed back to the running of PLC arrestment.And the impurity such as ink (9) to push hinge contact hypomere (11) open, thus the situation well solving erroneous judgement occurs.
